The complaint also seeks costs and attorney fees. The matter was stayed by the court in 2008 to allow for the remediation of environmental areas at the site.  On June 30, 2016, the U.S. District Court for the District of Delaware ordered the stay lifted and reopened the case. Discovery was completed in the third quarter of 2019. Trial was bifurcated and moved to September 2021 for Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") issues and to a later undetermined date for questions of fact.  At this stage, we cannot predict the ultimate outcome of this action or estimate a range of reasonably possible losses related to this matter. </span></div><div style="margin-top:12pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Ravenswood Retiree Medical Benefits </span></div><div style="margin-top:12pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In November 2009, Century Aluminum of West Virginia ("CAWV") filed a class action complaint for declaratory judgment against the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union ("USW"), the USW&#8217;s local and certain CAWV retirees, individually and as class representatives ("CAWV Retirees"), seeking a declaration of CAWV&#8217;s rights to modify/terminate retiree medical benefits.&#160;Later in November 2009, the USW and representatives of a retiree class filed a separate suit against CAWV, Century Aluminum Company, Century Aluminum Master Welfare Benefit Plan, and various John Does with respect to the foregoing.&#160; On August 18, 2017, the District Court for the Southern District of West Virginia approved a settlement agreement in respect of these actions, pursuant to which agreement, CAWV agreed to make payments into a trust for the benefit of the CAWV Retirees in the aggregate amount of $<ix:nonFraction unitRef="usd" contextRef="if4ddea740a034166b98b05f94e95407b_D20170818-20170818" decimals="-5" format="ixt:numdotdecimal" name="us-gaap:LitigationSettlementAmountAwardedToOtherParty" scale="6" id="id3VybDovL2RvY3MudjEvZG9jOmVhYWU5YjgxZmFjZjQyZDA4NDRmNGFmYmRjMzA4OGVlL3NlYzplYWFlOWI4MWZhY2Y0MmQwODQ0ZjRhZmJkYzMwODhlZV82MS9mcmFnOjJlOGFjODQxMmY5MjQ5OWFiY2M1YTExOTcyNGFjZGU3L3RleHRyZWdpb246MmU4YWM4NDEyZjkyNDk5YWJjYzVhMTE5NzI0YWNkZTdfMzkzNQ_5f60e6cb-a32a-4d73-8177-766b3e4f48d0">23.0</ix:nonFraction> million&#160;over the course of <ix:nonNumeric contextRef="if4ddea740a034166b98b05f94e95407b_D20170818-20170818" format="ixt-sec:durwordsen" name="cenx:LitigationSettlementPeriod" id="id3VybDovL2RvY3MudjEvZG9jOmVhYWU5YjgxZmFjZjQyZDA4NDRmNGFmYmRjMzA4OGVlL3NlYzplYWFlOWI4MWZhY2Y0MmQwODQ0ZjRhZmJkYzMwODhlZV82MS9mcmFnOjJlOGFjODQxMmY5MjQ5OWFiY2M1YTExOTcyNGFjZGU3L3RleHRyZWdpb246MmU4YWM4NDEyZjkyNDk5YWJjYzVhMTE5NzI0YWNkZTdfMzk1Nw_f09acbe5-6c77-4b5d-a9af-f9d39c3f53ff">ten years</ix:nonNumeric>.

From time to time, we may manage our exposure to fluctuations in the LME price of primary aluminum and/or the regional premium through financial instruments designed to protect our downside price risk exposure.

Certain of the alumina we purchase is priced based on a published alumina index.  As a result, our cost structure is exposed to market fluctuations and price volatility.  Because we sell our products based principally on the LME price for primary aluminum, regional premiums and value-added product premiums, we are not able to directly pass on increased production costs to our customers. From time to time, we may manage our exposure to fluctuations in our alumina costs by purchasing certain of our alumina requirements under supply contracts with prices tied to the same indices as our aluminum sales contracts (the LME price of primary aluminum). </span></div><div style="margin-top:9pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Market-Based Power Price Sensitivity</span></div><div style="margin-top:9pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Market-Based Electrical Power Agreements</span></div><div style="margin-top:9pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Hawesville and Sebree have market-based electrical power agreements pursuant to which EDF and Kenergy purchase electrical power on the open market and pass it through at MISO energy pricing, plus transmission and other costs incurred by them.

These power purchase agreements, which will expire on various dates from 2023 through 2036 (subject to extension), primarily provide power at LME-based variable rates.

Power represents one of our largest operating costs, so changes in the price and/or availability of market power could significantly impact the profitability and viability of our operations.  Transmission line outages, problems with grid stability or limitations on energy import capability could also increase power prices, disrupt production through pot instability or force a curtailment of all or part of the production at these facilities.  In addition, indirect factors that lead to power cost increases, such as any increasing prices for natural gas or coal, fluctuations in or extremes in weather patterns or new or more stringent environmental regulations may severely impact our financial condition, results of operations and liquidity.</span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">36</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> </span></div></div><div style="margin-bottom:15pt;margin-top:9pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The consumption shown in the table below reflects each operation at 100% capacity and does not reflect partial production curtailments.</span></div><div style="margin-bottom:6pt;margin-top:12pt"><table style="border-collapse:collapse;display:inline-table;vertical-align:top;width:99.707%"><tr><td style="width:1.0%"></td><td style="width:29.838%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:11.949%"></td><td style="width:0.1%"></td><td style="width:0.1%"></td><td style="width:0.826%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:11.949%"></td><td style="width:0.1%"></td><td style="width:0.1%"></td><td style="width:0.533%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:11.949%"></td><td style="width:0.1%"></td><td style="width:0.1%"></td><td style="width:0.826%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:11.949%"></td><td style="width:0.1%"></td><td style="width:0.1%"></td><td style="width:0.826%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:11.955%"></td><td style="width:0.1%"></td></tr><tr><td colspan="3" style="padding:0 1pt"></td><td colspan="3" style="padding:2px 1pt;text-align:center;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:100%">Hawesville </span></td><td colspan="3" style="padding:0 1pt"></td><td colspan="3" style="padding:2px 1pt;text-align:center;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:100%">Sebree</span></td><td colspan="3" style="padding:0 1pt"></td><td colspan="3" style="padding:2px 1pt;text-align:center;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:100%">Mt.

You should carefully consider the risk factors set forth below and those contained in our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q and our other filings made with the Securities and Exchange Commission.

A portion of the proceeds from the issuance of the Convertible Notes and the 2028 Notes were used to repurchase $195.9 million of the 2025 Notes tendered in  a cash tender offer and to pay down revolving credit facilities, and the balance of the proceeds will be used to redeem the $54.1 million of the 2025 Notes that were not tendered in the tender offer on May 14, 2021.  Our ability to pay interest on and to repay or refinance our debt will depend upon our access to additional sources of liquidity and future operating performance, which is subject to general economic, financial, competitive, legislative, regulatory, business and other factors, including market prices for primary aluminum, that are beyond our control. Accordingly, there can be no assurance that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to pay debt service obligations, refinance our existing debt or to fund our other liquidity needs. If we are unable to meet our debt service obligations or fund our other liquidity needs, we could attempt to restructure or refinance our debt or seek additional equity or debt capital. There can be no assurance that we would be able to accomplish those actions on satisfactory terms, or at all. If we are unable to ultimately meet our debt service obligations and fund our other liquidity needs, it may have a material adverse effect on our business, financial position, results of operations and liquidity.</span></div><div style="margin-top:9pt;text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Conversion of the Convertible Notes may dilute the ownership interest of our stockholders or may otherwise depress the price of our common stock.</span></div><div><span><br/></span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The conversion of some or all of the Convertible Notes may dilute the ownership interests of our stockholders.

Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In general, reporting entities should apply valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. Observable inputs are developed using market data and reflect assumptions that market participants would use when pricing the asset or liability. Unobservable inputs are developed using the best information available about the assumptions that market participants would use when pricing the asset or liability.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The fair value hierarchy provides transparency regarding the inputs we use to measure fair value.

However, because of the nature and inherent uncertainties of litigation and estimating liabilities, should the resolution or outcome of these actions be unfavorable, our business, financial condition, results of operations and liquidity could be materially and adversely affected. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In evaluating whether to accrue for losses associated with legal or environmental contingencies, it is our policy to take into consideration factors such as the facts and circumstances asserted, our historical experience with contingencies of a similar nature, the likelihood of our prevailing and the severity of any potential loss.&#160;&#160;For some matters, no accrual is established because we have assessed our risk of loss to be remote.&#160;&#160;Where the risk of loss is probable and the amount of the loss can be reasonably estimated, we record an accrual, either on an individual basis or with respect to a group of matters involving similar claims, based on the factors set forth above. While we regularly review the status of, and our estimates of potential liability associated with, contingencies to determine the adequacy of any associated accruals and related disclosures, the ultimate amount of loss may differ from our estimates.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Legal Contingencies&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Vernon&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In July 2006, we were named as a defendant, together with certain affiliates of Alcan Inc., in a lawsuit brought by Alcoa Inc. seeking to determine responsibility for certain environmental indemnity obligations related to the sale of a cast aluminum plate manufacturing facility located in Vernon, California, which we purchased from Alcoa Inc. in December 1998, and sold to Alcan Rolled Products-Ravenswood LLC in July 1999. The complaint also seeks costs and attorney fees. The matter was stayed by the court in 2008 to allow for the remediation of environmental areas at the site.  On June 30, 2016, the U.S. District Court for the District of Delaware ordered the stay lifted and reopened the case. Discovery was completed in the third quarter of 2019. Trial was bifurcated and moved to September 2021 for Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") issues and to a later undetermined date for questions of fact.  At this stage, we cannot predict the ultimate outcome of this action or estimate a range of reasonably possible losses related to this matter. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Ravenswood Retiree Medical Benefits &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In November 2009, Century Aluminum of West Virginia ("CAWV") filed a class action complaint for declaratory judgment against the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union ("USW"), the USW&#x2019;s local and certain CAWV retirees, individually and as class representatives ("CAWV Retirees"), seeking a declaration of CAWV&#x2019;s rights to modify/terminate retiree medical benefits.&#160;Later in November 2009, the USW and representatives of a retiree class filed a separate suit against CAWV, Century Aluminum Company, Century Aluminum Master Welfare Benefit Plan, and various John Does with respect to the foregoing.&#160; On August 18, 2017, the District Court for the Southern District of West Virginia approved a settlement agreement in respect of these actions, pursuant to which agreement, CAWV agreed to make payments into a trust for the benefit of the CAWV Retirees in the aggregate amount of $23.0 million&#160;over the course of ten years.  Upon approval of the settlement, we paid $5.0 million to the aforementioned trust in September 2017 and recognized a gain of $5.5 million to arrive at the-then net present value of $12.5 million.  CAWV has agreed to pay the remaining amounts under the settlement agreement in annual increments of $2.0 million for nine years. As of March&#160;31, 2021, $2.0 million was recorded in other current liabilities and $7.7 million was recorded in other liabilities.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;PBGC Settlement&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In 2013, we entered into a settlement agreement with the Pension Benefit Guarantee Corporation ("PBGC") regarding an alleged "cessation of operations" at our Ravenswood facility. Pursuant to the terms of the agreement, we agreed to make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17.4 million. Under certain circumstances, in periods of lower primary aluminum prices relative to our cost of operations, we are able to defer one or more of these payments, provided that we provide the PBGC with acceptable security for such deferred payments. We did not make any contributions for the three month periods ended &lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;March&#160;31, 2021,&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; and 2020. We have elected to defer certain payments under the PBGC agreement and have provided the PBGC with the appropriate security. The remaining contributions under this agreement are approximately $9.6 million. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Environmental Contingencies&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Matters relating to the St. Croix Alumina Refining Facility&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We are a party to a United States Environmental Protection Agency Administrative Order on Consent (the "Order") pursuant to which certain past and present owners of an alumina refining facility at St. Croix, Virgin Islands (the "St. Croix Alumina Refinery") have agreed to carry out a Hydrocarbon Recovery Plan to remove and manage hydrocarbons floating on groundwater underlying the facility.&#160;&#160;Pursuant to the Hydrocarbon Recovery Plan, recovered hydrocarbons and groundwater are delivered to the adjacent petroleum refinery where they are received and managed. In October 2020, parties participating in the Hydrocarbon Recovery Plan filed a complaint against Century and Virgin Islands Alumina Corporation, L.L.C. relating to the Hydrocarbon Recover Plan.  The deadline to respond to the complaint has been postponed by all parties until May 27, 2021.    At this time, we are not able to estimate the amount of any future potential payments under this indemnification to comply with the Order, but we do not anticipate that any such amounts will have a material adverse effect on our financial condition, results of operations or liquidity, regardless of the final outcome.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; In December 2010, Century was among several defendants named in a lawsuit filed by plaintiffs who either worked, resided or owned property in the area downwind from the St. Croix Alumina Refinery. In March 2011, Century was also named a defendant in a nearly identical suit brought by certain additional plaintiffs. The plaintiffs in both suits allege damages caused by the presence of red mud and other particulates coming from the alumina facility and are seeking unspecified monetary damages, costs and attorney fees as well as certain injunctive relief. We tendered indemnity and defense to St. Croix Alumina LLC and Alcoa Alumina &amp;amp; Chemical LLC under the terms of an acquisition agreement relating to the facility and have filed motions to dismiss plaintiffs&#x2019; claims. In August 2015, the Superior Court of the Virgin Islands, Division of St. Croix denied the motions to dismiss but ordered all plaintiffs to refile individual complaints. On February 28, 2018, plaintiffs in both cases filed a Motion for Voluntary Dismissal of Century without prejudice to refiling. At this time, it is not possible to predict the ultimate outcome of or to estimate a range of reasonably possible losses for any of the foregoing actions relating to the St. Croix Alumina Refinery.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Power Commitments and Contingencies&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Hawesville&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Hawesville has a power supply arrangement with Kenergy and EDF Trading North America, LLC (&#x201c;EDF") which provides market-based power to the Hawesville smelter.  Under this arrangement, the power companies purchase power on the open market and pass it through to Hawesville at Midcontinent Independent System Operator ("MISO") pricing plus transmission and other costs.  The power supply arrangement with Kenergy has an effective term through December 2023.  The arrangement with EDF to act as our market participant with MISO has an effective term through May 2022.  Each of these agreements provide for automatic extension on a year-to-year basis unless a one year notice is given.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Sebree&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Sebree has a power supply arrangement with Kenergy and EDF which provides market-based power to the Sebree smelter.

The power purchase agreements with HS and OR both provide power at LME-based variable rates for the duration of these agreements.  The power purchase agreement with Landsvirkjun for 161 MW provides power at rates linked to the Nord Pool power market.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:12pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Helguvik&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Nordural Helguvik ehf ("Helguvik") has a power purchase agreement with OR to provide a portion of the power requirements to the Helguvik project.  The agreement would provide power at LME-based variable rates and contain take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreement.  The first phase of power under the OR purchase agreement (approximately 47.5 MW) became available in the fourth quarter of 2011 and is currently being utilized at Grundartangi.

These contracts are expected to settle monthly through December 2024. We also had an open position of 418,500 tonnes related to Midwest Premium ("MWP") forward financial sales contracts to fix the forward MWP price. These contracts are expected to settle through December 2022. We have also entered into financial contracts with various counterparties to offset fixed price sales arrangements with certain of our customers ("fixed for floating swaps") to remain exposed to the LME and MWP aluminum prices.  As of March 31, 2021, we had 16,482 tonnes related to fixed for floating swaps that will settle at various dates through March 2022. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We previously have entered into financial contracts to hedge a portion of our exposure at our U.S. operations to the NYMEX Henry Hub ("NYMEX Henry Hub natural gas price swaps").

As of March 31, 2021, we had an open position of 1,815,075 MWh related to the Nord Pool power price swaps. The Nord Pool power price swaps are expected to settle monthly through December 2023. Because the Nord Pool power price swaps are settled in Euros, we have entered into financial contracts to hedge the risk of fluctuations associated with the Euro ("FX swaps").  As of March 31, 2021, we had an open position related to the FX swaps of &#x20ac;42.2 million that will settle monthly through December 2023. &lt;/span&gt;&lt;/div&gt;&lt;div

The Convertible Notes were issued at a price of 100% of their aggregate principal amount, will pay interest semi-annually in arrears on May 1 and November 1 of each year, beginning on November 1, 2021, at a rate of 2.75% per annum in cash, and will mature on May 1, 2028, unless earlier converted, repurchased or redeemed.  The Convertible Notes are Century&#x2019;s senior unsecured obligations and rank senior in right of payment to any of Century&#x2019;s indebtedness that is expressly subordinated in right of payment to the Convertible Notes; equal in right of payment to any of Century&#x2019;s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of Century&#x2019;s senior, secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of Century&#x2019;s subsidiaries.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On April 14, 2021, we completed our offering of $250.0&#160;million aggregate principal amount of the 2028 Notes. The 2028 Notes bear interest semi-annually in arrears on each April 1 and October 1 of each year, beginning on October 1, 2021, at a rate of 7.5% per year.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Concurrently with the closing of the issuance of the 2028 Notes, on April 14, 2021, we accepted for purchase and purchased $195.9&#160;million in aggregate principal amount of the 2025 Notes pursuant to a tender offer commenced in connection with the offering; and we notified the holders of all outstanding 2025 Notes that were not purchased in the tender offer of our election to redeem all such remaining 2025 Notes on May 14, 2021, and deposited with the trustee under the indenture governing the 2025 Notes an amount sufficient to fund the full redemption of the remaining 2025 Notes and discharge our obligations with respect thereto. We applied a portion of net proceeds from the offering of the 2028 Notes described above toward payment of the total consideration amount to holders whose 2025 Notes were accepted and purchased in the tender offer and the remaining proceeds from the issuance of the 2028 Notes and a portion of the net proceeds from the Convertible Notes will be used to fund the redemption of any remaining 2025 Notes, which will be redeemed on May 14, 2021. The remaining proceeds from the Convertible Notes offering were used to repay borrowings under our revolving credit facilities and to pay for the cost of the capped call transactions in connection with the issuance of the Convertible Notes. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Based on the characteristics of the 2025 Notes and the 2028 Notes that were issued, the tender and redemption of the 2025 Notes would be accounted for as an extinguishment of the debt. Accordingly, we expect to record a loss on early extinguishment of debt in the second quarter of 2021, consisting of the write-off of deferred financing costs of $4.4&#160;million and the debt discount of $2.2&#160;million associated with the 2025 Notes, as well as the tender fees, including a tender premium of $14.6&#160;million, paid as part of the tender offer.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-indent:18pt"&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On April 16, 2021, a new, five-year collective bargaining agreement was ratified by the United Steelworkers Local 9423 for the Company's Hawesville, Kentucky smelter.

The complaint also seeks costs and attorney fees. The matter was stayed by the court in 2008 to allow for the remediation of environmental areas at the site.  On June 30, 2016, the U.S. District Court for the District of Delaware ordered the stay lifted and reopened the case. Discovery was completed in the third quarter of 2019.

Upon approval of the settlement, we paid $5.0 million to the aforementioned trust in September 2017 and recognized a gain of $5.5 million to arrive at the-then net present value of $12.5 million.

In August 2015, the Superior Court of the Virgin Islands, Division of St. Croix denied the motions to dismiss but ordered all plaintiffs to refile individual complaints.

These contracts are expected to settle monthly through December 2024. We also had an open position of 418,500 tonnes related to Midwest Premium ("MWP") forward financial sales contracts to fix the forward MWP price. These contracts are expected to settle through December 2022. We have also entered into financial contracts with various counterparties to offset fixed price sales arrangements with certain of our customers ("fixed for floating swaps") to remain exposed to the LME and MWP aluminum prices.  As of March 31, 2021, we had 16,482 tonnes related to fixed for floating swaps that will settle at various dates through March 2022. </span></div><div style="margin-top:9pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We previously have entered into financial contracts to hedge a portion of our exposure at our U.S. operations to the NYMEX Henry Hub ("NYMEX Henry Hub natural gas price swaps").

Because the Nord Pool power price swaps are settled in Euros, we have entered into financial contracts to hedge the risk of fluctuations associated with the Euro ("FX swaps").
